Amazing watching the NASA clips from the mission around the moon. A little fact about the astronauts while in space :
Most people think of protein needs in simple terms:
➡️ Sedentary = weight (kg) × 0.8
➡️ Athlete = weight (kg) × ~1.4
But here’s something fascinating…
🚀 Astronauts in space require about 1.2–1.7 g/kg of protein per day
At first glance, you might think:
“They should need MORE… not similar to athletes?”
But the reason is actually the opposite—and it’s incredibly educational.
In space, the body is in a catabolic state:
• Muscle breaks down faster
• Bone density decreases
• There is minimal gravitational resistance
So protein isn’t used to build—it’s used to prevent loss.
💡 On Earth, athletes:
• Train under resistance
• Create muscle damage → repair → growth
• Use protein to build and perform
💡 In space, astronauts:
• Fight muscle loss
• Use protein to preserve what they have
Here’s the takeaway I share with my patients:
👉 If you’re not strength training… your body behaves more like an astronaut than an athlete.
Which means:
• Low protein = muscle loss
• Muscle loss = slower metabolism, hormonal imbalance, aging faster
✨ Protein isn’t just for athletes—it’s for longevity.
If your goal is:
✔️ Healthy weight
✔️ Strong metabolism
✔️ Aging well
Then your protein intake matters more than you think.
